This is not in fact a windmill as you might think, but a wind machine.

"Wind machines are tall, fixed-in-place, engine-driven fans that pull warm air down from high above ground during a strong thermal inversion, raising air temperatures around cold-sensitive crops such as grapes." (American Society of Agricultural and Biological Engineers)

They are all over the peninsula, not unattractive but they have as many critics as supporters. The sound pollution they produce is quite considerable.
